		10	`int pushssl(int fd, char alg, char secin, char secout, int cfd)`
		11	`.SH DESCRIPTION`
		12	`.I Pushssl`
		13	`opens an`
		14	`.IR ssl (3)`
		15	`device, connects it to the communications channel`
		16	`.IR fd ,`
		17	`and starts up encryption and message authentication as specified`
		18	`in`
		19	`.IR alg .`
		20	`The algorithms are separated by a space and either can be first.`
		21	`See`
		22	`.IR ssl (3)`
		23	`for the possible algorithms.`
		24	`.I Secin`
		25	`and`
		26	`.I secout`
		27	`contain the encryption keys for the two directions.`
		28	`If either is nil, the other is used in both directions.`
		29	`If`
		30	`.I cfd`
		31	`is non-nil, the SSL control channel is opened and its fd`
		32	`returned.`
		33	`.PP`
		34	`.I Pushssl`
		35	`returns a file descriptor for the SSL data channel. Anything written to this`
		36	`descriptor will get encrypted and authenticated and then written to the`
		37	`file descriptor,`
		38	`.IR fd .`
